  • the pitches in the vertical direction and the horizontal direction are variously different, it is possible to generate a parallax image in which the left-eye regions 18L and the right-eye regions 18R are considered as being divided and arranged on the display screen in a substantially random manner.
  • the parallax image generated using the above-mentioned parallax image generation method may be output as a parallax image print by printing the parallax image on a paper sheet through an unshown printer or the like as well as being displayed on the parallax image display unit 12 of the parallax image display device 10.
  • the present invention relates to a space-division stereoscopic display and does not require electrical driving.
  • a polarizing film corresponding to the left-eye region 18L and the right-eye region 18R of the parallax image is pasted on the printed parallax image.
  • an elliptical polarizing plate described in JP 2009-193014 A can be used as the polarizing film.
  • the elliptical polarizing plate can be manufactured with an arbitrarily-changed polarization pattern, the elliptical polarizing plate of which the polarization pattern corresponds to the left-eye region 18L and the right-eye region 18R is manufactured and pasted on the parallax image as the polarizing film.
  • the parallax image print on which the polarizing film is pasted By viewing with the polarized glasses 14 the parallax image print on which the polarizing film is pasted, an observer recognizes only the left-eye image with the left eye through the polarizing lens 14L and recognizes only the right-eye image with the right eye through the polarizing lens 14R, and accordingly, the observer can perform a stereoscopic view on the basis thereof as described above.
  • parallax image display device the parallax image generation method, and the parallax image print according to the present invention have been described in detail, the present invention is not limited to the above-mentioned aspects and may be improved or modified in various forms without departing from the scope of the present invention.
